Project description
A generic client for RESTful APIs based on aiohttp. Python 3.5+ only.
Installation
$ pip install genericclient-aiohttp
Quickstart
import asyncio
from genericclient_aiohttp import GenericClient
async def main():
myclient = GenericClient(api_url)
myresource = await myclient.resources.get(id=1)
actives = await myclient.posts.filter(active=True)
loop = asyncio.get_event_loop()
loop.run_until_complete(main(loop))
Usage
Instantiation
myclient = GenericClient(url, auth=None, session=None, trailing_slash=False)
Arguments:
url: The root URL of your API
auth: The auth for your API. You can pass anything that aiohttp.ClientSession can accept as auth.
session: Pass a session instance to have aiohttp use that session. If None (the default), it will instantiate an instance of aiohttp.ClientSession for you.
trailing_slash: You can set this to True if your API’s URLs end with a /
Endpoints
Endpoints are available as properties on the main instance.
.all()
Retrieves all resources (essentially a simple GET on the endpoint):
await myclient.posts.all() # GET /posts/
.filter()
.filter(**kwargs) calls a GET with kwargs as querystring values:
await myclient.posts.filter(blog=12, status=1) # GET /posts/?blog=12&status=1
.get(**kwargs)
A special case of .filter().
If kwargs contains id, pk, slug or username, that value will be used in the URL path, in that order.
Otherwise, it calls a GET with kwargs as querystring values.
If the returned list is empty, will raise ResourceNotFound.
If the returned list contains more than 1 resource, will raise MultipleResourcesFound
Note that .get() will return a Resource, not a list of Resource s
await myclient.posts.filter(blog=12, status=1) # GET /posts/?blog=12&status=1 await myclient.posts.filter(id=12) # GET /posts/12/ await myclient.posts.filter(slug='12-ways-clickbait') # GET /posts/12-ways-clickbait/
.create(payload)
Will result in a POST, with payload (a dict) as the request’s body, returning a new Resource:
post = await myclient.posts.create({'blog': 12, 'status': 1}) # POST /posts/
.get_or_create(defaults, **kwargs)
Issues a GET to fetch the resource. If the resource is not found, issues a POST to create the resource:
# Assuming it doesn't exist
post = await myclient.posts.get_or_update(slug='my-post', defaults={'status': 1}) # GET /posts/my-post/, then POST /posts/
.create_or_update(payload)
If payload contains a key called 'id', will issue a PUT. If the server returns a 400 error, a PATCH request will be re-issued. If payload` does not contains 'id', it will issue a POST:
post = await myclient.posts.create_or_update({'status': 1}) # POST /posts/
post = await myclient.posts.create_or_update({'id': 1234, 'status': 1}) # PUT /posts/1234/
post = await myclient.posts.create_or_update({'id': 1234}) # PUT /posts/1234/
# <- server returns 400
# -> PATCH /posts/1234/
.delete(pk)
Will issue a DELETE, and will use pk as part of the URL:
await myclient.posts.delete(24) # DELETE /posts/24/
Resources
All endpoints methods (with the exception of .delete()) return either a Resource or a list of Resource s.
A Resource is just a wrapping class for a dict, where keys can be accessed as properties.
Additionally, Resource s have a special property called .payload, which contains the original payload received from the server.
Resource s have the following methods:
Resource.delete() will result in a DELETE, with Resource.id as par of the URL:
blog = await myclient.posts.create({'blog': 12, 'status': 1}) # POST /posts/
await blog.delete() # DELETE /blog/345/ -- the ID 345 was returned by the server in the previous response
Resource.save() will result in a PUT, with Resource.id as par of the URL. If the server returns a 400 error, a PATCH request will be re-issued:
post = await myclient.posts.create({'blog': 12, 'status': 1}) # POST /posts/
post.status = 2
await post.save() # PUT /posts/345/
post = Resource(id=345, status=1)
await post.save() # PUT /posts/345/
# <- server returns 400
# -> PATCH /posts/345/
ResourceSets
Whenever a method returns a list of Resources, they list will be wrapped in a ResultSet.
A ResultSet is a just a list object, with the addition of a .response containing the original response from the server.
Routes
If your API has some non-RESTful calls within the main endpoints (sometimes referred as detail_route and list_route), you can use genericclient to call them:
await myclient.posts(id=123).publish(date=tomorrow),
await myclient.blogs().ping()
Routes http calls use POST by default, but you can specify something else by using the _method argument:
await myclient.posts(_method='get', id=123).pingbacks(),
await myclient.blogs(_method='get').visits()
Note that instead of instances of genericclient_aiohttp.Resource, this calls will return an instance of aiohttp.web.Response.
